본 발명은 소각시설용 액상소석회 공급펌프 및 배관 세척장치 에 관련되며, 보다 상세하게는 펌프 및 배관을 분해하지 않고 구연산 세정액을 순환하는 방식으로 소석회를 세척하도록 구조 개선되어, 소석회 고착으로 인한 배관 막힘 및 펌프 고장을 방지할 수 있고, 특히, 간단한 조작으로 세척공정이 수행되어 세척시간 단축 및 세척 비용을 크게 절감 할 수 있는 소각시설용 액상소석회 공급펌프 및 배관 세척장치에 관한 것이다.The present invention relates to a liquid slaked lime supply pump and a pipe washing device for an incineration facility, and in more detail, the structure is improved to clean slaked lime in a way that circulates citric acid washing liquid without disassembling the pump and pipe, It is possible to prevent pump failure, and in particular, to a liquid sintered lime supply pump and pipe washing device for incineration facilities that can reduce the cleaning time and greatly reduce the cleaning cost by performing a cleaning process with a simple operation.

통상적으로 쓰레기 소각장치는 생활 쓰레기를 연소시켜 처리하는 장치로서, 생활 쓰레기를 연소할 때에 발생되는 열원은 재생에너지로 사용될 수 있고, 연소시 발생되는 다양한 환경오염물질을 정화하기 위한 공정이 반드시 구비되어야 한다.In general, a waste incinerator is a device that burns and treats household waste, and a heat source generated when burning household waste can be used as renewable energy, and a process for purifying various environmental pollutants generated during combustion must be provided. .

즉, 생활 쓰레기 등을 소각하는 소각로의 배출가스 속에는 연소과정을 통해 발생한 비산재, 산성가스(HCl, SO2 ,HF, H2S등), 질소산화물(NO, NO2 등), 중금속(Hg, As, Pb 등), 다이옥신류(PCDD, PCDF 등) 및 휘발성 유기가스(VOC) 등의 유해 대기오염물질이 포함되어 있는데 이러한 오염 물질은 대기중으로 배출되기 전에 반드시 규제치 이하로 처리되어야 한다.That is, in the exhaust gas of the incinerator that incinerates household waste, fly ash generated through the combustion process, acid gases (HCl, SO2, HF, H2S, etc.), nitrogen oxides (NO, NO2, etc.), heavy metals (Hg, As, Pb, etc.) ), dioxins (PCDD, PCDF, etc.), and volatile organic gas (VOC), and other harmful air pollutants are included.

이에 종래에 개시된 등록특허 10-1160469호에서, 소각로; 상기 소각로에서 배출된 배가스의 폐열을 이용하여 난연성 폐기물을 건조하는 건조기(400); 상기 소각로에서 배출된 배가스가 상기 건조기를 통과하면서 생성된 증기 및 온수가 저장되는 용수공급설비; 상기 용수공급설비로부터 공급된 물을 이용하여 가동되는 폐열보일러; 및 상기 폐열보일러로부터 유입된 배가스가 서로 인접한 공간을 최장거리 경로로 이동하면서 각각의 공간에서 분사된 액상 소석회 슬러리와 순차적으로 반응하면서 중화될 수 있도록 상부에는 배가스 유입구가 형성되고, 하부에는 제1반응물 배출구가 형성되며, 상기 배가스 유입구 일측에는 제1액상 소석회 슬러리 분사노즐이 장착된 제1챔버와, 상부 일측에는 제2액상 소석회 슬러리 분사노즐이 장착되고, 하부에는 제2반응물 배출구가 형성된 제2챔버와, 상기 제1챔버와 제2챔버를 구획하되 그 하단에는 제1배가스 취출구가 형성된 제1분리벽을 포함하는 다단계 반건식 반응탑;을 포함하고, 상기 소각로에서 배출된 소각재는 그 내부에 냉각수가 흐르는 냉각기에서 냉각된 후, 상기 건조기에서 건조 배출된 난연성 폐기물과 혼합압착기에서 혼합압착되고, 상기 냉각기를 순환한 후에 배출된 고온의 냉각수는 상기 용수공급설비로 유입되는 기술이 선 제시된 바 있다.Accordingly, in the conventionally disclosed Patent Registration No. 10-1160469, an incinerator; A dryer 400 for drying flame-retardant waste by using the waste heat of the exhaust gas discharged from the incinerator; A water supply facility for storing steam and hot water generated while the exhaust gas discharged from the incinerator passes through the dryer; A waste heat boiler operated using water supplied from the water supply facility; And a flue gas inlet is formed in the upper part and a first reactant in the lower part so that the flue gas introduced from the waste heat boiler can be neutralized while sequentially reacting with the liquid slaked lime slurry sprayed from each space while moving through the space adjacent to each other in the longest path. An outlet is formed, a first chamber equipped with a first liquid slaked lime slurry injection nozzle is mounted on one side of the exhaust gas inlet, a second liquid slaked lime slurry injection nozzle is mounted on one side of the upper side, and a second chamber having a second reactant discharge port is formed at the lower side. And, a multi-stage semi-dry reaction tower that divides the first chamber and the second chamber, and includes a first separation wall having a first exhaust gas outlet at a lower end thereof, wherein the incineration ash discharged from the incinerator contains cooling water therein. After being cooled in a flowing cooler, the flame-retardant waste dried and discharged from the dryer is mixed and compressed in a mixing press, and the high-temperature cooling water discharged after circulating the cooler is introduced into the water supply facility.

그러나 상기 종래기술은 산성 가스를 효율적으로 중화시키려는 것이나, 액상소석회를 공급하는 펌프와 공급배관에 소석회가 고착시 소석회 분사압력이 저하됨과 더불어 펌프, 배관 막힘현상이 발생되고, 이로 인해 주기적으로 펌프, 배관을 모두 분해한 상태로 청소해야 하므로 불필요한 시간과 노동력 손실이 발생되며, 특히, 소석회 고착으로 펌프 고장시 교체에 따른 유지관리비용이 증가되는 폐단이 따랐다.However, the prior art is to effectively neutralize the acid gas, but when the slaked lime is fixed to the pump and the supply pipe for supplying the liquid slaked lime, the injection pressure of the slaked lime decreases, and the pump and the pipe are clogged. Since the pipes must be cleaned in a disassembled state, unnecessary time and labor losses occur. In particular, when the pump breaks down due to the sticking of slaked lime, the maintenance cost increases due to replacement followed.

It includes a return line 50 that can be recovered to the 10) side.

또한, 본 발명에 따른 세정조(100)는 내부에 구연산 세정액이 수용되고, 하부에 구연산 세정액이 토출되는 토출포트(110)와, 상부에 구연산 세정액이 회수 투입되는 회수포트(120)가 구비된다.In addition, the cleaning tank 100 according to the present invention is provided with a discharge port 110 through which the citric acid cleaning solution is accommodated and the citric acid cleaning solution is discharged at the lower portion, and a recovery port 120 through which the citric acid cleaning solution is recovered and injected in the upper portion. .

상기 세정조(100)는 원심분리수단(700)에 의해 구연산 세정액에 포함된 소석회 고형물을 침전 분리하도록 구비된다.The washing tank 100 is provided to precipitate and separate the slaked lime solids contained in the citric acid washing liquid by a centrifugal separation means 700.

도 4에서, 상기 원심분리수단(700)은, 토출포트(110)에 일단이 연결되고, 다른 일단은 세정조(100) 중앙으로 연장되어 상방향으로 절곡된 상태로 상단부에 구연산 세정액 유입구(712)가 형성되는 수직관(710)과, 회수포트(120)에 일단이 연결되고, 다른 일단은 세정조(100) 내주면을 따라 경사각으로 형성되어, 구연산 세정액이 경사각으로 출력되면서 세정조(100) 내에 구연산 세정액을 회전시키는 와류발생노즐(720)과, 수직관(710)에 삽입되어 종방향으로 길이 조절되고, 상단에 멀티 유입구(732)가 형성되는 멀티수직관(730)과 세정조(100) 내에서 부력에 의해 구연산 세정액 수면에 부양되고, 연결대(742)에 의해 멀티수직관(730)에 연결되는 부력체(740)를 포함한다.In FIG. 4, the centrifugal separation means 700 has one end connected to the discharge port 110, and the other end extends to the center of the washing tank 100 and is bent upward, and the citric acid washing liquid inlet 712 at the upper end thereof. ) Is formed, one end is connected to the recovery port 120, and the other end is formed at an inclined angle along the inner circumferential surface of the washing tub 100, so that the citric acid washing solution is output at an inclined angle, and the washing tub 100 A vortex generating nozzle 720 for rotating the citric acid cleaning solution inside, and a multi-vertical pipe 730 and a washing tank 100 that are inserted into the vertical pipe 710 and adjusted in length in the longitudinal direction, and have a multi-inlet 732 formed at the top. ) It is floated on the surface of the citric acid washing solution by buoyancy within, and includes a buoyancy body 740 connected to the multi-vertical pipe 730 by a connecting rod 742.

이처럼 상기 세척과정을 거친 후 회수포트(120)를 통하여 세정조(100) 내부로 출력되는 구연산 세정액에 의해 세정조(100) 내부에 와류가 발생되면서 원심분리에 의해 구연산 세정액에 포함된 소석회 고형물이 세정조(100) 내주면으로 이동되어 하향 침전 분리되고, 이때 소석회 고형물이 분리된 구연산 세정액은 세정조(100) 중앙에 배치되는 수직관(710)을 통하여 흡입되어 세정공정을 수행하는 순환 과정을 거치므로, 장시간 사용에도 세정액이 오염도가 개선되어 세척효율이 향상된다.As described above, after the above washing process, a vortex is generated in the washing tank 100 by the citric acid washing solution that is output into the washing tank 100 through the recovery port 120, and the slaked lime solids contained in the citric acid washing solution are removed by centrifugation. The washing tank 100 is moved to the inner circumferential surface of the washing tank 100 and is sedimented downward. At this time, the citric acid washing liquid from which the slaked lime solid is separated is sucked through the vertical pipe 710 disposed in the center of the washing tank 100 and undergoes a circulation process in which the washing process is performed Therefore, even when used for a long time, the degree of contamination of the cleaning solution is improved, thereby improving the cleaning efficiency.

그리고, 상기 세정조(100) 내에 저장된 구연산 세정액 수위에 따라 부력체(740) 높낮이가 조절되면서 멀티수직관(730)의 멀티흡입구(732)와 구연산 세정액 수면 사이 거리(L)가 일정하게 유지되도록 구비된다.In addition, while the height of the buoyancy body 740 is adjusted according to the level of the citric acid cleaning solution stored in the cleaning tank 100, the distance L between the multi-intake port 732 of the multi-vertical tube 730 and the surface of the citric acid cleaning solution is kept constant.
